Understand the degree to which a Sense of Community at School can predict the Life Satisfaction of Chilean students in the fifth and seventh grades. The classroom and school components will be presented separately. The research was designed as a descriptive study using a survey with a probabilistic sample made up of 1959 students (52.

Material And Methods: We evaluated 211 ER+ advanced BC (ABC) patients, treated between 1997 and 2017.
Results: The median overall survival (OS) was 37 months.
Breast cancer (BC) is the most common malignancy in women. We retrieved medical records from >2,000 Chilean BC patients over the 1997-2018 period. The objective was to assess changes in clinical presentation or prognosis of our patients throughout these 20 years of practice.

It can be the first manifestation of a tumor predisposition syndrome. Prompt diagnosis will allow for the implementation of early screening techniques for associated malignancies.

Based on studies showing the potential role of heme oxygenase-1 (HO-1), an enzyme that catalyzes the degradation of heme and has anti-inflammatory properties in SLE development, we decided to explore HO-1 in LN. Accordingly, we evaluated HO-1 levels and function in circulating and infiltrating monocytes and neutrophils of LN patients.

Here, the therapeutic potential of transferring tolerogenic dendritic cells (tolDCs) generated with heme-oxygenase inductor cobalt (III) protoporphyrin IX (CoPP), dexamethasone and rosiglitazone for the treatment of systemic autoimmunity was evaluated in two murine models of systemic lupus erythematosus (SLE), MRL-Fas and NZM2410 mice. Dendritic cells treated ex vivo with these drugs showed a stable tolerogenic profile after lipopolysaccharide stimulation.

The aim of our study was to determine a relationship between the neutrophil to lymphocyte ratio (NLR) prior to NAC, BC subtypes and the probability of a pathologic complete response (pCR). Materials and Methods: Medical records were collected retrospectively from Centro de Cancer at Red Salud UC-Christus.

The aim of this paper is to compare histological diagnosis by percutaneous biopsy with the results of the surgical biopsy of these lesions and to analyse the changes to clinical approach this would imply.
Method: A retrospective study was carried out on patients operated on between June 2007 and June 2017 with a diagnosis of BLA.
Background: HER2+ breast cancer (BC) subtype overexpresses the Human Epidermal growth factor Receptor type-2 (HER2) and is characterized by its aggressiveness and its high sensitivity to monoclonal antibody-based HER2-targeted therapies.
Aim: To assess the prognosis and evaluate the impact of novel anti-HER2 therapies on advanced HER2+ BC patients treated at our institution over the last decades.
Material And Methods: Analysis of the patient database at a cancer center of a university hospital.
Granulomatous lobular mastitis is a rare disease whose origin is still unknown and shows an increase in its frequency. Morphological, microbiological, and molecular biology studies have linked this disease to lipophilic and fastidious corynebacteria, suggesting its possible infectious etiology. This series describes and reviews in detail the distinctive morphological characteristics of the bacteria present in the granulomas of this disease, the usefulness of histochemical techniques for their identification, and our proposal for a tissue quantification score for the bacteria.

To date, there are no reliable biomarkers to effectively predict patient prognosis. Studies have demonstrated inflammation and tumor infiltrating lymphocytes (TILs) correlate with a bad and good prognosis, respectively.

Objective: To evaluate histological grade and Eliminate: the mitotic index to determine if they can be used as an alternative method to Ki67 staining for luminal subtype definition. Methods: We evaluated estrogen receptor positive breast cancer tissue samples.
